Most of us are fans of 8-bit machines, as I am. However, in looking
in Wikipedia, I ran across this item as it relates to Unix Time:
"At 15:30:08 UTC on Sun, 4 December 292,277,026,596 64-bit versions
of the Unix time stamp will cease to work, as it will overflow the
largest value that can be held in a signed 64-bit number. For these
systems, the next second will once again be incorrectly indicated as
Thursday, 1 January 1970 at 00:00:00. This is, however, considerably
longer than the time it would take the Sun to theoretically expand to
a red giant and swallow the earth."
Yeah... the year is expressed in 12 decimal digits. Since the solar
expansion is expected to take place about 288 billion years before
Unix runs out of bits, that makes the roll-over a very moot point.
